d. When the correct adjustment is reached, lock the rear roller guide in position with the guide adjusting screw (D) Fig.16 Guide adjusting screw (C) 9. CHANGING THE DRIVE BELT a. Release the saw blade tension by turning the blade tension knob on the top of bandsaw counterclockwise. b. Using a M6 hex. "L" wrench (not 15rovided) to release the hex. socket head cap screw on motor mounting flange. (See Fig. 17) c. Using a clip pliers (not provided) remove the retaining ring from the center of the lower wheel. d. Carefully slide the lower wheel forward and at the same time release the saw blade from this wheel. e. Remove the old drive belt and fit the new belt. (ensure ribs in drive belt are seated correctly before reassembling and tensioning the drive belt) f. Follow procedures for CHANGING AND ADJUSTING THE SAW BLADE & TRACKING THE BANDSAW BLADE, before restoring power to the bandsaw and setting up for use. WARNING: Before starting check if any part of your bandsaw is missing, malfuctioning, has been damaged or broken.., such as the motor switch, or other operation control, a safety device or the power cord, turn the bandsaw off and unplug it until the particular part is properly repaired or replaced. The saw blade cuts on a continuous downstroke, To avoid injury when hands are unavoidably near to the saw blade, they should be placed on either side of the blade, not in line with it. Use a push stick whenever possible when working in close proximity to the saw blade. For best results the saw blade must be sharp. Select the right saw blade for the job, depending on_tthe thickness of the wc.od the cut to be made. The thinner and harder the wood, the finer the teeth of the saw blade. Use a fine tooth blade for cutting sharp curves. The machine is especially suited for cutting curves, but will also make straight cuts. Do not attempt to turn the workpiece without pushing it, as this may cause the workpieee to get stuck, or the saw blade to bend. The rip fence is to enable safe and accurate straight cuts of the workpiece, usually in the same direction as the grain of the timber. Start the bandsaw by turning the lock switch on and wait for the bandsaw to come to full speed before starting to cut. Never start the bandsaw with the workpiece in contact with the saw blade. Slowly feed the workpiece towards the saw blade, putting only light pressure on it. With both hands, firmly hold the workpiece down on the table, and feed it towards the saw blade slowly. The miter gauge is to enable safe and accurate crosscut of the workpiece. The tiltable table is used for bevel cuts. WARNING: When sawing with the rip fence and a tilted table, the rip fence must be installed on that side of the table which is tilted downward. WARNING: To avoid injury due to unexpected starting, before cleaning or carrying out maintenance work, switch off and disconnect the bandsaw from the power source. Never use water or other liquids to clean the bandsaw. Use a dry brush. Regular maintenance of the bandsaw will prevent unnecessary problems. a. Keep the table clean to ensure accurate cutting. b. Keep the outside of the machine clean to ensure accurate operation of all moving parts and prevent excessive wear. c. Keep the ventilation slots of the motor clean to prevent it from overheating. d. Keep the inside (near the saw blade, etc.) clean to prevent accumulation of dust. Use dust collection if possible. e. To prolong the life of the saw blade, when the bandsaw is not in use for extended periods, release the saw blade tension. Before reusing the bandsaw ensure that the blade is re-tensioned and tracking is checked. 8

by turning
the blade tension
knob on the top of bandsaw
counterclockwise.
b. Using a M6 hex. "L" wrench
(not 15rovided) to release the hex.

(See Fig. 17)
c. Using a clip pliers
(not
provided)
remove
the retaining
ring from
the center of the lower wheel.
d. Carefully
slide the
lower wheel forward
and at the same time
release the saw
blade from this wheel.
e. Remove
the old drive belt and fit the new belt. (ensure
ribs in
drive belt are seated
correctly
before
reassembling
and tensioning
the drive belt)
f. Follow procedures
for CHANGING
AND ADJUSTING
THE SAW
BLADE & TRACKING
THE BANDSAW
BLADE,
before restoring
power to the bandsaw
and setting
up for use.
WARNING:
Before
starting check
if any part of your bandsaw
is
missing,
malfuctioning,
has been
damaged
or broken..,
such
as
the motor switch,
or other operation
control, a safety device
or the
power
cord, turn the
bandsaw
off and unplug
it until the particular
part is properly
repaired
or replaced.
The saw
blade cuts
on a continuous
downstroke,
To avoid
injury
when
hands
are unavoidably
near to the
saw blade,
they
should
be placed on either side of the blade,
not in line with it. Use a
push stick
whenever
possible
when
working
in close proximity
to
the
saw blade.
Start the bandsaw
by turning the
lock switch
on and wait for the
bandsaw
to
come to full speed
before starting to cut. Never start
the bandsaw
with the workpiece
in contact
with the saw blade.
Slowly
